A bar code scanner which is sealed against moisture and dust intrusion. The scanner includes a housing having a base portion and a lid portion. A mirror basket is located within the base portion. A seal between the lid portion and the base portion prevents dust and fluids from entering the mirror basket and the housing when the lid is secured to the base portion. A circuit board seal prevents dust and fluids from entering an aperture in the mirror basket through which a laser and a detector on the circuit board protrude.
